Cain says Christie too liberal for conservatives

Republicans unhappy with the current field of GOP presidential contenders have been urging Christie to run. Christie has resisted becoming a candidate, but those close to the governor say he is reconsidering his decision to stay out of the race.

Cain tells "Fox News Sunday" that many conservatives won't support Christie once they find out about his views on global warming, illegal immigrants and gun control.

Christie has broken with traditional conservative views on some issues. He has voiced support for some gun control, has said being in the country without proper documentation is not a crime, and has called climate change real and partially manmade.
